COMBING-MAGHINE I Patented Aug. 2'7, 1907.

Application filed January 24,1907- Serial No. 353,866.

To all whom it may concern: I

Be it known that I, ELWIN I-I. RooNn Y, a citizen of the United States, and a resident of New Bedford, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Combing-Machines, of which the following is a full, true, and concise specification.

My invention relates to cotton combing machines and more particularly to an improved means for preventing the draft of air generated by the revolving combing cylinder from escaping beneaththe lower piecing roll, and the invention involves to this end a scraper member located beneath the said roll and closing the space between the same and the waste chute, as will be hereinbelow fully described and finally pointed out in the claims.

In the accompanying two sheets of drawings which form a part of this specification, Figure l is a transverse sectional view of parts of a cotton combing machine of a well known type, and Fig. 2 is a side elevation of Fig. 1 with parts broken away, and both said figures show my invention in place.

As will be recognized by those skilled in this art, the reference character 1 designates the combing cylinder which cooperates with the leather detaching roll 2, the lower roll 3 and the upper roll 4, to detach and piece the combed staple which emerges between the rolls 3 and 4 in the form of a continuous ribbon. The

upper roll 4 is journaled in horse-tails 5 at each end andthe latter are pivoted in the yoke 6 carried by the longitudinal rod 7. The clearing cover 8 carried in notches in the horse tail rests as usual upon the two uppermost piecing rolls and is contiguous to the top comb 9. The waste chute, designated by the numeral 10, and which constitutes the inclosure for the cylinder 1, its cleaning brush 11, and other waste removing apparatus not shown, is supported at its upper end bymeans of bracket lugs 12 engaging the rod 7. The drawings show for convenience only the front wall of the chute, but it will be understood that the same is of usual construction and may have any appropriate means of support.

In accordance with my invention I mount upon the top margin of the waste chute a plate 13, preferably of soft material like felt, which substantially closes the space between said chute and the lower roll and prevents the escape at this point of the air within the chute, which latter is set into violent commotion by the combing cylinder, especially in high speed machines. The plate 13, which may be termed a scraper, is mounted upon the waste chute, either permanently or adjustably, so that its upper edge is in close proximity to the roll, but it need not necessarily be in rubbing contact therewith. Its means of support upon the chute consists, in the example shown, of a holder 14 formed of a strip of sheet metal bent into U-shape and soldered to the inside margin of the chute, the scraper being held in the holder by gravity or by friction against its sides. Other means for supporting and holding the scraper in position however may be resorted to with equal effect, provided the scraper or its holder or both shall serve to obstruct the air passage as above explained.

In the practical use of the foregoing device the scraper is most conveniently made slightly wider than required in the first instance and allowed to wear down to proper height by the abrasion of the roll upon it.

By virtue of the location of the scraper directly beneath the lower roll it may be extended the full distance between the journals of the lower roll and thereby the combing cylinder and waste removing apparatus may be completely inclosed on the front side and moreover the discharge of the lint and combings into the room is thus effectively prevented.

Having described my invention, what I claim and desire to secure by United States Letters Patent is:

1. In a combing machine, the-combination of the lower piecing roll and waste chute, with a scraper for said roll mounted upon the waste chute and adapted to obstruct the escape of air from within said chute.

In a combing machine; the combination of the lower piecing roll and waste chute, with a holder secured to the margin of said chute and a scraper in said holder adapted for contact with said roll.

3. In a combing machine, the combination of the lower piecing roll and waste chute, with a scraper for said roll, mounted beneath the same and extending longitudinally thereof the distance between its journals, said scraper being adapted to obstruct the escape of air between said roll and the waste chute.

In testimony whereof, I have signed my name to the specification in the presence of two subscribing witnesses.

ELWIN H. RODNEY.
